“Can I actually retire at 50?”
The data shows Alex crossing financial independence around age 46 — ahead of the age-50 goal. The threshold is not a guess: spending sets it. At $4,500/month, the plan needs $1,493,342 after-tax to sustain itself — and every year of the chart shows the portfolio walking toward that line.
Change the spending and the target moves with it, live. That reactivity is the point: the answer is a consequence of the inputs, with the math showing.
“Where does my $150K actually go?”
RunwayFI computes the full stack from the actual rules: gross $150,000 → a $22,500 pre-tax 401(k) deferral → the $16,100 standard deduction → federal taxable income of $111,400. Federal tax $19,334, FICA $11,475, Illinois $6,166 — total $36,975, leaving $113,025 post-tax (24.7% effective).
The same stack renders live in the app and recomputes as inputs change — the trust layer is being able to check the math, not being asked to believe it.
“Is a savings rate like mine actually enough?”
Alex’s plan computes a 49% savings rate — the single number that most directly drives the FI age. The engine treats it as an output of real cash flows (take-home $9,419/mo, spending $4,500/mo, 401(k) $1,875/mo), not a slider someone sets optimistically.
The verdict line on Alex’s briefing reads: “Financial Independence at ≈46 — the day work becomes optional” — recomputed every time an input changes.
